I update two data one text data and two file data but it's not working this. How to update file?
My code is:
public function update(Request $request){
$news=new News();
$news->newstitle=$request->newstitle;
$url1=$this->imageExistStatus1($request);
$news->save();
return redirect()->back()->with('sms','insert successful');
}
public function imageExistStatus1($request){
$newsByid1=News::where('id',$request->newsid)->first();
$fimage1=$request->file('imageone');
if ($fimage1) {
unlink($newsByid1->imageone)
$thisName1= $fimage1->getClientOriginalName();
$uplodePath1='public/up/';
$fimage1->move($uplodePath1,$thisName1);
$url1=$uplodePath1.$thisName1;
}else{
$url1=$newsByid1->imageone;
}
return $url1;
}
First, change your code to the following
public function update(Request $request, $id)
{
$news = News::findOrFail($id);
$news->newstitle = $request->newstitle;
$fimage1 = $request->file('imageone');
if ($fimage1) {
unlink($news->imageone);
$news->imageone = $this->imageExistStatus1($request, $id);
}
$news->save();
return redirect()->back()->with('sms', 'insert successful');
}
public function imageExistStatus1($request)
{
$fimage1 = $request->file('imageone');
$thisName1 = $fimage1->getClientOriginalName();
$uplodePath1 = 'public/up/';
$fimage1->move($uplodePath1, $thisName1);
$url1 = $uplodePath1 . $thisName1;
return $url1;
}
I hope your problem is resolved
tip:
Thanks to "Oluwatobi Samuel Omisakin".
please use the route:
Route::patch('/news/{id}/update', 'NewsController#update')

I am using method post to create new data in xml file but The function c_element cannot be used in the function store
$DeTai = c_element('DeTai', $root);
This is my current code:
public function c_element($e_name, $parent)
{
global $xml;
$node = $xml->createElement($e_name);
$parent->appendChild($node);
return $node;
}
public function c_value($value, $parent)
{
global $xml;
$value = $xml->createTextNode($value);
$parent->appendChild($value);
return $value;
}
public function store(Request $request)
{
$xml = new DOMDocument("1.0","UTF-8");
$xml->load('../xml/QuanLyDoAnTotNghiep.xml');
if ($request->isMethod('post'))
{
$madt= $request->madt;
$noidungdetai = $request->noidungdetai;
$root=$xml->getElementsByTagName("QuanLyDoAnTotNghiep")->item(0);
$DeTai = c_element("DeTai", $root); //error in here
$s_madt = c_element('MaDT', $DeTai);
c_value("$madt", $s_madt);
$s_noidungdetai = c_element('NoiDungDeTai', $DeTai);
c_value("$noidungdetai", $s_noidungdetai);
$xml->formatOutput=true;
$xml->save('../xml/QuanLyDoAnTotNghiep.xml');
echo "Thêm mới thành công!!!";
}
}
use this keyword to call one method in different method of same class
$DeTai = $this->c_element('DeTai', $root);

I want to make a filter with query params, here I want to make 3 where, but if one of them is not there, then it will not be a problem because it will display according to the filter only, and if there is no query string then it will display all data
public function VendorInfoFilter(Request $request)
{
$vendor = DB::table('schema.data as d')
->where('d.status','=',$request->status)
->orderBy('d.id')
->get();
return response()->json($vendor);
}
Take as reference, exact code might not work for you.
public function VendorInfoFilter(Request $request)
{
$vendor = DB::table('schema.data as d');
if (!empty($request->status_one)) {
$vendor = $vendor->where('d.status','=', $request->status_one);
}
if (!empty($request->status_two)) {
$vendor = $vendor->where('d.status','=', $request->status_two);
}
if (!empty($request->status_three)) {
$vendor = $vendor->where('d.status','=', $request->status_three);
}
if (empty($request->status_one) && empty($request->status_two) && empty($request->status_three)) {
$vendor= $vendor->where('d.status','=', $request->status_one)->where('d.status','=', $request->status_two)->where('d.status','=', $request->status_three);
}
$result = $vendor->orderBy('d.id')
->get();
return response()->json($result);
}
public function VendorInfoFilter(Request $request)
{
$vendor = DB::table('schema.data as d')
->when($request->status, function ($q, $status) {
return $q->where('d.status','=', $status);
})
->when($request->status_two, function ($q, $status_two) {
return $q->where('d.status_two','=', $status_two);
})
->orderBy('d.id')
->get();
return response()->json($vendor);
}
public function orderlist(Request $request){
$id = $request->id;
$data['order'] = Order::where('shop_id',$id)->orderBy('id')->get();
foreach($data['order'] as $orders){
$orders->shop = Shop::where('id',$orders->shop_id)->first();
$orders->food = Food::where('id',$orders->food_id)->get();
}
return $orders->food->name;
return view ('administrator.users.list_order.index',$data);
}
If you set up proper Eloquent relationships, this code could be rewritten like so:
public function orderlist(Request $request, Shop $shop){
$orders = $shop->orders()->with(['food'])->get();
return view ('administrator.users.list_order.index',compact('orders'));
}
Check out the docs here: https://laravel.com/docs/5.7/eloquent-relationships
I have a given table :
tools toolparts parts part_details
----- --------- ----- ------------
id* id* id* id*
name tool_id name part_id
part_id total (int)
----- --------- ----- ------------
the relation between Tools and Parts is ManyToMany. and the relation between parts and part_details is one to many.
with Laravel model, how can I get tool with part that has the biggest part_details.total ??
//tool model
public function parts()
{
return $this->belongsToMany('App\Part', 'tool_part');
}
//part model
public function tools()
{
return $this->belongsToMany('App\Tool', 'tool_part')
}
public function details(){
return $this->hasMany('App\Part_detail');
}
//partDetail model
public function part(){
return $this->belongsTo('App\Part');
}
Controller
public function index()
{
$tools = Tool::with('parts', 'parts.details')->has('parts')->get();
return $tools;
}
what I expected is something like :
Controller
public function index()
{
$tool = Tool::with('SinglePartThatHasHigestTotalInPartDetail');
}
Any Idea ??
You can use Laravel aggregates for querying to get the desired result,
In your code use max() function,
public function index()
{
$tool = Tool::with(['parts.part_details' => function ($query) {
$max = $query->max('total');
$query->where('total',$max);
})->first();
}
I haven't tested this but you can do like this.
Comment if you will get any errors.
I Manage my problem with "hacky" ways. if someone have a better and more elegant solution, please tell me.
//tool model
public function partWithHighestTotalDelivery($trans_date = null){
if (is_null($trans_date)) {
$trans_date = date('Y-m-d');
}
$parts = $this->parts;
$highest_total_delivery = 0;
foreach ($parts as $key => $part) {
$part->detail;
$total_delivery = $part->first_value;
if (isset( $part->detail->total_delivery )) {
$total_delivery += $part->detail->total_delivery;
}
if ($highest_total_delivery < $total_delivery ) {
$highest_total_delivery = $total_delivery;
$part->total_delivery = $highest_total_delivery;
$result = $part;
}
}
if (!isset($result)) {
$result = null;
}
$this->part = $result;
}
In controller i have :
public function index(Request $request){
$tools = Tool::has('parts')
->get();
$tools->each(function($tool){
$tool->partWithHighestTotalDelivery();
});
return $tools;
}
with this, I need to run tool->partWithHighestTotalDelivery() tools.count times. which is take noticeable process if the tools is many.
and also, the code I post and the question I ask has a slightly difference.that's for a simplicity sake's
Use the the hasManyThrough Relationship to get the all part details related to tool and then you can check the one by one record and get the highest total of the tool part.
// Tool Model
public function partsdetails()
{
return $this->hasManyThrough('App\PartDetail', 'App\Part','tool_id','part_id');
}
In Your controller
$data = Tool::all();
$array = [];
if(isset($data) && !empty($data)) {
foreach ($data as $key => $value) {
$array[$value->id] = Tool::find($value->id)->partsdetails()->max('total');
}
}
if(is_array($array) && !empty($array)) {
$maxs = array_keys($array, max($array));
print_r($maxs);// This array return the max total of the tool related parts
}
else{
echo "No Data Available";
}
You can start with the part detail and get the tool(s) from there:
$maxPartDetail = Part_detail::orderByDesc('total')->first();
$tools = $maxPartDetail->part->tools;
I am doing a filtering and searching in codeigniter but no idea! how to do that?
but i try my best but fail!!!
here i show the list which is shown by ajax that sucess
MY DATA BASE ARE
MY CONTROLLER IS
public function get_quick_search()
{
$sepcli= $this->input->post('spec');
$distct= $this->input->post('dist');
$locat= $this->input->post('locat');
$data['list'] = $this->Doctor_model->search_listing();
$data['quck_search'] = $this->search_model->get_quick_list($sepcli,$distct,$locat);
$data['get_specs'] = $this->specialisation_model->get_specialisation();
$this->load->helper(array('form', 'url'));
$this->load->view('customer/header');
$this->load->view('customer/side_view',$data);
$this->load->view('customer/quick_search',$data);
$this->load->view('customer/footer');
}
MY MODEL LIKE
public function get_quick_list($locat,$distct,$sepcli)
{
$this->db->select('*');
$this->db->from('tbl_doctor');
$this->db->join("tbl_specialisation", "tbl_specialisation.spec_id = tbl_doctor.spec_id",'left');
$this->db->where("(district LIKE '$distct' AND place LIKE '$locat' AND spec_specialise LIKE '$sepcli')");
$query=$this->db->get()->result_array();
return $query;
}
HERE NO ERROR SHOW BUT THE RETURN QUERY IS NULL SHOW LIKE THIS (array(0) { })
you might try like this ,Your Controller function code
public function get_quick_search()
{
$s_data['sepcli'] = $this->input->post('spec');
$s_data['distct'] = $this->input->post('dist');
$s_data['locat'] = $this->input->post('locat');
$data['quck_search'] = $this->search_model->get_quick_list($s_data);
$data['get_specs'] = $this->specialisation_model->get_specialisation();
$this->load->helper(array('form', 'url'));
$this->load->view('customer/header');
$this->load->view('customer/side_view',$data);
$this->load->view('customer/quick_search',$data);
$this->load->view('customer/footer');
}
your model function code
public function get_quick_list($s_data)
{
$this->db->select('td.*, ts.*')
$this->db->from('tbl_doctor as td');
$this->db->join('tbl_specialisation as ts', 'ts.spec_id = td.spec_id','left');
if($s_data['sepcli'] !="")
$this->db->like('ts.spec_specialise',$s_data['sepcli'],'both');
if($s_data['distct'] !="")
$this->db->like('td.district',$s_data['distct'],'both');
if($s_data['locat'] !="")
$this->db->like('td.place', $s_data['locat'], 'both');
$query=$this->db->get()->result_array();
return $query;
}
sure it will helps , you should try it !!!
